Hi all, I created environment "mytoolbox" by : mytoolbox <- new.env(parent=baseenv()) Is there anyway I put it in the search path ? If you need some background : In a project, I often write some small functions, and load them into my workspace directly, so when I list the objects with ls(), it looks pretty messy. So I am wondering if it is possible to creat an

Hello, I am trying to make a plot using the code below. The plot is divided into two parts, using facet_grid. I would like the vertical axis (labelled 'place') to be different for each location (=part). So in the upper part, only places 'n' through 'z' are shown, while in the lower part, only places 'a' through 'm' are shown. I thought 'free_y'

Hi All, I have been struggling to figure out how to compile c codes for R use. I am using Win XP + Cygwin + R binaries.

hi, I received this e-mail which contains a "ballad", at first I thought it was junk mail, but then I read through it, for the EE members of this list, it may be quite humorous.
